  1. Can anyone here help me?

    I have a 30 min video file from around 2009 that I cannot get to play. It used to play fine on my Mac, but not any more.

    I have tried multiple players (Flipformac, VLC, DivX etc) on a Mac and a PC, and different codecs etc but it will not play. The best I have got is picture, but no sound. The problem seems to be it has been encoded with WMA3 and WMV3 codecs (The error I keep getting in VLC is - "Codec not Supported").

    I have tried downloading and installing old version of Windows Media Player and VLC - still no good.

    I have pasted in the information below that the MediaInfo application gives me

    If anyone could get this working and send me a copy I would be willing to pay them

    if you can help, please send me a message and I will send you the file via DropBox

    Thanks all

    Still sounds like DRM. Or a corrupt file. Is this a video you purchased?

    And what do you mean by "will not play"? What exactly happens when you try to play it? Do you get an error message? Garbled picture? Sound?

    Players like VLC have WMV3 and WMA3 decoders built in. So it's not a codec problem.

  4. A week ago it would play with the picture fine, but no sound.

    Then I tried installing/updating different video players and codecs, and now all I get is either a blank screen, or an error message that says "Codec not supported, VLC could not decode the format WMA3" and "Codec not supported, VLC could not decode the format WMV3"

    I have tried it on a Mac (OS 1.11.6) and on a Win 7 PC

    I have tried:

    VLC
    Windows Media Player/Flip4mac
    DivX
    Realplayer
    Quicktime
    Elmedia player

  5. Try re-wrapping into the proper asf/wmv container format , maybe with ffmpeg

    WMV in MOV probably isn't very stable or compatible with many things

  7. ffmpeg -i "input.mov" -map 0 -c copy -f asf "output.asf"


    P.S.: Your MediaInfo version looks very outdated.

    Have you installed FFmpeg? Is it in your path?
    Quote Quote  
  10. yes, i have downloaded ffpgeg, but i still cant get it to work

    i am running the command from the ffmpeg folder

    sorry, this is all new to me
    Quote Quote  
  11. ok, i have downloaded FFmpeg, but i have no idea how to install it. i have two folders on my desktop, one called "ffmpeg-3.3" and "ffmpeg-3-1.3"

    what else do i have to do to get ffmpeg working?
    Quote Quote  
  12. ok,i have got ffmpeg installed and ran the following (input.mov is my movie)

    ffmpeg -i "input.mov" -map 0 -c copy -f asf "output.asf"


    i get this:

    Could not find codec parameters for stream 0 (Audio: none (WMA3 / 0x33414D57), 44100 Hz, 2 channels, 65 kb/s): unknown codec
    Consider increasing the value for the 'analyzeduration' and 'probesize' options
    Guessed Channel Layout for Input Stream #0.0 : stereo

    I would say your audio stream (and perhaps the whole file) is corrupt.

  14. ok thanks. this is very frustrating as i have seen the video in the past and have had no problems with my hard disk since

    You could try ffmpeg -codecs to get a list. I'm not sure it reads WMA3.
    Quote Quote  
  16. i just tried that and the only WMA that appear is

    D.A..S wmalossless Windows Media Audio Lossless
    D.A.L. wmapro Windows Media Audio 9 Professional
    DEA.L. wmav1 Windows Media Audio 1
    DEA.L. wmav2 Windows Media Audio 2
    D.A.L. wmavoice Windows Media Audio Voice

    Wikipedia tells me that WMA went from Version 2 to Version 7. MPlayer tells me that 0x33414D57 is the ID for WMA Pro Audio. Sounds like you have a corrupt or obsolete stream header. You could try going into the file (a copy!) with a byte editor and changing the FourCC to "WMA2" or "WMA9" and see what happens.

  18. any suggestions for a byte editor i can use?

  21. 33414D57 is the code for 3AMW (reverse WMA3). So JVRaines suggested changing it to 32414D57 and/or 39414D57. (I have no idea if that will work.)

    If you send me the file I can test it.

  22. 33414D57

    My suggestion was to search for the text string "WMA3" in the file and change it wherever it occurs.
    Quote Quote  
  24. i have changed all instances of "WMA" to "WMA2" - same problem

    and

    i have changed all instances of "WMA" to "WMA9" - same problem

    Hmm. I find very few references to "WMA3" on the 'net and they point to WMA Pro and Version 9. Maybe your file is stuck in versioning hell; I know that Microsoft monkeyed around with the version numbers quite a bit. Have you tried playing your file on a Windows machine with Windows Media Player? In particular, an older version of WMP? You might also give Windows Media Encoder a try.

    If this is not a sensitive file, could you post it to the forum?

  28. I verified that VLC can't play WMV and WMA2 in a MOV container (I don't have any WMA3 to test) even though it has no problems playing them from a WMV or MKV container.

    There is no WMA7 or WMA9 fourcc. The WMA library went from version 2 to 7 (and later to 9) but the fourcc didn't change to those numbers.

  29. here it is...

    if anyone can get it working i would be very pleased
